SPECIFICATIQN forming part of Letters Patent No. 290,317, dated December 18 1883.

Application filed October 5, 1883. (No model.)

To all whom it may concern:

, Be it known that I, CLARKE. CARR, acitizenof the United States, residing at Galesburg, in the county of Knox and State of Illinois, have invented certain new and useful Improvements in Car-Couplings; and I do hereby declare the following to be a-full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and y'use the same, reference being had to the accompanying drawings, and to letters or gures of reference marked thereon, which form a part of this specification.

My invention relates to railway-car couplings ofthe ordinary class known as link-andpin77 couplings; and the objects of my improvements are, first, to furnish means by which theoperator may, without going between the cars, hold the link insuch position that it will enter the draw-bar head with which a coupling is to be effected, and, second, to afford facilities, without the operator going between the cars, for raising the coupling-pin and holding it in an elevated position both for coupling and uncoupling. A

The first object of my invention is accomplished by means of a swinging arrn'provided with a shaft and lever, by means of which it may be raised to lift and hold the couplinglinkin position for coupling, and hinged orv journaled in such manner that when struck' by the adjacent draw-bar, when two draw-bars are brought together for coupling, this linksupporting arm will be driven backward and swing downward and out of the way.

The second objectl of my 4invention is accomplished by means of a rock-shaft and operating-lever, from which rock-shaft an arm extends and is connected at its outer end with a link or coupling-rod, which link is connected with the coupling-pin in such manner that by turning the shaft the coupling-pin will be raised and tilted backward at its Vupper end into the ordinary self-sustaining position.

A further feature of my invention consists in adapting the same rock-shaft and lever which operates the link-raising arm to also operate the coupling -pin raising devices, whereby vthe link may be raised without lifting the pin' and the Vpin raised without lifting the link, all as hereinafter fully described.

In the accompanying drawings, which illus- 'trate one method of applying my improvements to an ordinary car-coupling,` Figure 1 is a'perspective; Fig.`2, a perspective; Fig. 3,'a side elevation, partly in section; Fig. 4, a `side elevation; Fig. 5, a side elevation showing the parts' in different relative positions from that shown at Fig. 4L; Fig. 6, partly a sectional elevation and partly a side elevation, showing'the parts in same relative 'positions as shown at Fig. 5; Fig. 7, a perspective of the link-lifting arm; Fig. 8, a side elevation of thev link-lifting arm and section of rockshaft; Fig. 9, a detail ligure hereinafter referred to.

Referring to the drawings by letters, the same letter indicating the same part in the different figures, A represents a portion of one end of a car; B, a draw-bar; G, a coupling-link, and D a coupling-pin. The parts B C D constitute an ordinary link-and-pin coupling, and need not be any more fully herein described, as their manner of operation is well known.

E is Va rock-shaft located transversely to and beneath th'e end of the car, and journaled each of its ends, beyond the side of the car, with a hand-lever, c, (only one of which is Shown.) i v F are arms loosely seated on the shaft E* one at each side of the draw-bar. Each arm F has a slot, f, through which a pin, f', passes, to secure the arm F from movement endwise of said shaft, while itpermits limited rotation of the shaft without movement of said arm, and moves the arms Fwith the shaft when the pin comes in contact with the end of the slot. Each arm F has a link or connecting-rod, G, hinged or journaled at its lower end t'o the outer-end of said arm, and these links G are connected attheir upper ends by a rod, g, which passes through a hole in the upper end of the coupling-pin D. AEach arm F is bent upwardly and outwardly at itsV outer end tov forni av dog, f". When the coupling-pin is seated in the draw-bar, the normal positions of the dogs f are, as shown most plainly at'Fig. 2, not in contact with the links G; but when the shaft E is turned to raise the links G, and after theyV and the coupling-pin have been raised a short distance, these dogs Vwill come, respectively, in contact with said armsG and 'in any suitable pendants, e, and provided at IOO force them rearward as the shaft E is further turned, and thereby incline the coupling-pin rearwardly at its upper end, in which position its lower end will rest in the upper end of the hole through the draw-bar, so as to sustain it, as shown most plainly at draw-bar B in Fig. 6, as is commonly done in coupling cars, and in such manner that when the drawbars come in contactin coupling, the elevated coupling-pin will be thrown forward at its upper end by thejar, and will then drop into its seat in the draw-bar.

H is the swinging link lifter, having a slot, lz, at one end, one end, h', of which slot is enlarged, and the other end, h, contracted. A flattened portion, c", of the shaft E passes through the slot h. The flattened portion c of the shaft is of such size in its cross-section relatively tothe slot 71. that it can only enter the contracted part h of said slot when presented edgewise of its flattened portion thereto, as shown most plainly at Fig. 9, while the portion It of the slot will admit the portion c of the shaft, with its broader way transverse to the slot, as shown most plainly at Fig. 8. The outer or forward end, It", of the lifter H is turned upwardly and made broad, so that it will sustain the link, as hereinafter described.

For convenience in describing the operations of my car-coupling, I will further designate one of the draw-bars by the accented letter B', and will assume that two draw-bars are already coupled, as shown at Fig. 3. Vhile the draw-bars are coupled, and in fact at all times while the coupling-pin is in its vertical position in the draw-bar, the normal position of the link-lifter H is vertical, as shown at Fig. 3, and the liattened portion c of the shaft E rests in the enlarged part h of the sloth, while the lever c also stands in its normal position, designated by the letter e with a figure l after it, to indicate the first position of said lever, as shown at same figure. To uncouple, one of the coupling-pins may be raised by turning the lever c to the position shown by a figure 2 after its reference-letter c', to designate its second position, as shown at Fig. 4. In turning the lever c, and with it the shaft E, as last described, the flattened portion e of the shaft will rotate in the enlarged part of the sloth, and hence not move the link-lifter H. To effect a coupling, one of the coupling-pins is raised to its elevated position, as last described for uncoupling, (see drawhea-d B at Figs. 5 and 6,) where it is sustained by the inclined position of the coupling pin in the hole in the draw-head, as also hereinbefore described. rlhe lever e of the draw-head B is then turned up to its third positiondesig nated by a figure 3 after its reference-letter 6'- whieh turns the shaft E so that its flattened portion e permits the link-lifter H to fall to a lower plane, and thus bring the portion e of the shaft into the contracted portion h of the slot, as shown by dotted lines at Fig. 3,

when, by turning the lever e downward to its fourth position, (shown at Figs. 2, 5, and 6,) the rotation of the shaft c will raise the link-lifter and hold the link C in the elevated position at its outer end, (shown at same figures,)in which position it will enter the draw-head B as the two draw-headsare brought together. As the draw-heads approach each other, and after the link cntersthehead B,theheadl3 willstrike the outer end of the lifter H, and,driving it backward, as shown by dottedlines at Fi 6,the slot h will slide on the shaft E until the iiattened portion of said shaft is in the enlarged part of the slot, when the lifter H will fall to its normal position, (shown by broken lines at same iigure,) and thej ar ofthe draw-heads or bumpers coming together will drop the elevated coup ling-pin, as hereinbefore described, and thus effect the coupling.

The use of the slotf and pinf may be de scribed as follows: When the lever c is in its first position, the pin j" will be near the rear end of the slot j', as shown at Figs. l and 2, and hence as the shaft E is turned rearwardly the pin in contact with the rear end of the slot will raise the arms F and coupling-pin, as hereinbefore described. The slot f will also permit turning the shaft E in the opposite direction from that last described without mov ing the arms F, when said shaft is so turned backward to allow the link-lifter to fall to a lower plane, so that it maybe swung upwardly, as hereinbefore described.

By means of this invention an operator may couple and uncouple carsin which any ordinary link and pin7 is used without going between the cars.

That I claim as new, and desire to secure by Letters Patent, is-.
